Class IndexOceanClient

                         IndexOceanClient

This class wraps around a regular ocean instance and manages multiple indexes (based on key-types) and makes available functions which take advantage of the indexes.

This frees Poseidon from actually handling index specific activities.

This class takes care of all issues pertaining to transactioning to make sure that Poseidon doesn't have to worry about it
